Grow muscles on top of your muscles!
I started out going to the gym 7 months ago just using a basic protein powder from my local gnc. When I ran out and went back to purchase another tub the sales person referenced me to this product saying it is a great addition to the whey powder I was using. I was pretty skeptical at first especially by the unattractive price tag so, he knocked the price down a little more for me and told me if I wasn't satisfied he would exchange it for a refund. It was a win win for me, after about 3 weeks of using this powder mixed in my whey I gotta say there was a HUGE difference! I could lift more and for longer durations! Little after a month I gained almost 3 pounds of muscle too! It may not sound like much but it shows a difference in strength. If you're serious about working out and gaining weight or muscle I would totally recommend this product!
